This invention relates to concrete wall construct-ion and has to do with improvements in the construction of the wall itself as well as in a method or succession of steps for carrying it out.

The objects of the invention are to provide a concrete wall for general building construction which will be easier to erect, cheaper than solid concrete walls, and more durable than former slab walls, and a simpler method of erecting such walls.

Briefly described my invention consists of a novel slab type concrete wall in which special slabs of a couple of inches in thickness are secured in vertical relation edge to edge and locked into reinforced concrete columns poured in place, and the method of carrying out the work.

The drawings hereto illustrate the preferred embodiment of my invention, the different views being as follows.

Figure 1 is an elevation of one of the slabs in the position it would occupy in a building wall with horizontal reinforcing bars projecting at both ends and the vertical bars terminating flush with the ct ges of the slab;

Figure 2 is an elevation of a short length of a building wall erected with the slabs of Figure 1 and the other features of my invention;

Figure 3 is an enlarged horizontal section of a portion of the wall of Figure 2;

Figure 4 is an enlarged detail showing a column in cross section and the joining of the slabs therewith;

Figure 5 is a similar view showing the inside half of the column casting form or mold erected with the column reinforcement in position and also with the slabs in place wired to the rear half of the mold;

Figure 6 is a view similar to the showing of Figure 5 but shows the front half of the column mold secured in place ready to pour the column for locking the slabs in place.

The slabs are all to be reinforced with vertical bars 5 terminating flush with the edges of the slab and horizontally extending bars 6 projecting beyond both ends of the slabs, also in some cases U-shaped wires 7 are imbedded in the slabs for the subsequent fas- Serial No. 43,363.

tening thereto of intermediate studs as at 8 in Figure 3.

Vhile the slabs are curing in the molds, forms are erected for casting the columns 9. First the rear or inside half 10 of the form is erected and suitably braced, after which any suitable spiral and vertical column reinforcing such as at 11 is placed in position, and also a nailing strip of wood 12 to be left imbedded in the rear wall of the column for securing the inside Wall covering.

After the half molds are erected the cured slabs 20 are placed against the forward edges of the sides of the mold with the slabs projecting into the column space as shown in Figure 5 and fastened tightly against the mold by wires 13 passing through holes in the rear mold member, and the reinforcing bars 6 are overlapped within the columns as indicated.

lVhen the slabs are secured to the rear half of the column molds as described the forward half 10 of the molds are clamped in place against the slabs by bolt studs 14 and the columns are poured with a comparatively rich wet concrete containing no very coarse aggregate, and after setting the forms are removed and the studs cut off flush with the walls.

Imbedded in the top of each column and projecting therefrom is an anchor bolt 15 for securing a plate 16 to the top of the wall and to which plate the ceiling joists and rafters are secured in the well known manner.

By reference to Figure 3 it will be observed that the columns project forwardly of the wall as well as rearwardly, this looks the slabs firmly into place and also gives the face of the wall a desirable panelled effect, and which is best covered with a cement wash, or stucco, to conceal all the joints.

The inward or rearward projection of the columns is greatest so as to provide a maximum dead air space after the inside wall finish is applied and which may consist of the plaster board nailed directly to the strips 12 though preference is given to a rigid ribbed metal lath 17 supporting the plaster 18.

Intermediate studs 8 may be used if desired,

and if used they are secured to the slabs by the U-shaped wires 7 as indicated.

Instead of the interior finish being plaster,

it may consist of relatively thinner slabs of concrete 19 cast flush with the rear wall of the columns as indicated at the right hand end of Figure 3 and the surface given a finishingcoat as desired.

Such thinner'slabs of concrete for the inio'terior finish could be cast in the same molds as used for the main outer slabs if desired by leaving oil a thickness of the mold ed e, though if desired the interior slabs being lighter may be made in a yard at a distance and transported to the building site.

In contemplating the invention as outlined above it will be seen to comprise more than the mere structure disclosed as a new method of concrete slab building construction is revealed which does away entirely with the great waste of lumber entailed when walls are cast in place and also does away with the long expensive hauls of wall slabs made at a distance.

I claim 1. A wall construction comprising a plurality of blocks superimposed upon each other so that the lower edge of one block rests upon the upper edge of the block disposed there- ??9 beneath, columns formed of a self-hardening material, and disposed between adjacent rows of blocks and having longitudinally eXtending grooves for receiving the edges of the blocks, U-shaped members carried by the blocks, a stud disposed in said U-shaped members, and a Wall covering overlying said columns and being secured to said studs.

2. A Wall construction comprising a plu ralit'y of blocks superimposed upon each other Q so that the lower edge of one block rests upon the upper edge of the block disposed therebeneath, columns formed of a self-hardening material, and disposed between adjacent rows of blocks and having longitudinally extending grooves for receiving the edges of the blocks, U-shaped members carried by the blocks, a stud disposed in said U-shaped members and a wall covering overlying said columns and being secured to said studs and studs ill'lbGClClQCl in the columns, and being secured to the wall covering.

3. A wall construction comprising aplurality of blocks super-imposed upon each other, U-shaped members carried by said blocks, and a stud disposed in said Ll-shaped members.

4. A wall construction comprising a plurality of blocks super-imposed upon each 7 other, U-shaped members carried by said blocks, a stud disposed in said U-shaped members, and a wall covering overlying said blocks and being secured to said stud.
